AIR CLEANER AND COLLECTOR.

Application filed December 2-3, 1926. Serial No. 156,719.

The invention relates to a device for cleaning and collecting air, primarily for the purpose of supplying it to the carbureter'of an automobile, motor truck or tractor, and the invention relates further to a device placed in the path of the air driven rearwardly by the usual tan, said device being of such nature that only clean air can enter it to pass to the carbureter.

It is the principal object of the invention to provide a new and improved device of the class set forth, which is rather simple and inexpensive, yet will be efficient and in every way desirable.

Vith the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed; the description being supplemented by the accompanying drawing.

Fig. 1 is an elevation partly in section showing the application of one form of the invention to an internal combustion motor.

Fig. 2 is an elevation as indicated by line Fig. 3 is a view similar to Fig 1 but illustrating a different form of construction.

Fig. 4: is a vertical sectional view on line 13-13 of Fig. 3.

In the form of construction shown in Figs. 1 and 2, the numeral 5 designates an arcuate suction pipe having attaching bases 6 and 7 at its ends, adapted to be secured by cap screws or the like 8, to a suitable part 9 of an internal combustion engine 10, the pipe 5 then occupying a position in which it is behind the usual fan 11 and is in a plane parallel to the plane of rotation of said fan. The side of the pipe 5 which faces away from the fan, is formed with a longitudinal slot 12 forming an air inlet. The end of the pipe 5 which connects with the base 6, communicates with an air outlet 13 with which said base is provided, while the opposite end of the pipe 5 may well be closed by the base 7 The outlet 13, in the present disclosure, communicates with an air heater 14 from which a pipe 15 leads to the carbureter.

The air driven rearwardly by the tan 11,

is divided by the pipe 5 and the compara-' tively heavy particles of dust or grit, cannot shunt from their rearward paths sutficiently to enter the slot 12, it being thus insured that the suction of the engine pistons and cylinders shall draw only clean air into the pipe 5 through said slot. This air of course mixes in the usual way with the fuel and the mixture is fed to they engine cylinders. As the air is free from dust, grit and the like, there is no danger of clogging delicate nozzles and other parts of the carbureter and moreover, the cylinders, pistons and valves are not subjected to the abrading influence of such foreign matter.

Preferably, the pipe 5 is integrally joined to the bases 6 and 7, and the outlet 130i the base 6 is integral with the remainder of this base and with the adjacent pipe end.

In the form of construction shown in Figs. 3 and 4, a hollow attaching base 6 is shown to be secured'by suitable fasteners 8 to a portion 9 of the engine 10'. The base 6 is provided with two opposed inlets 16 and with an outlet 1*? atright angles thereto, the latter being in communication with a pipe 15 leading to the carbureter. The ends of a pipe 5', which pipe is bent into'circular form, are secured to and communicate with the inlets 16, and said pipe is formed in the side which faces away from the fan 11, with a slot 12 which extends longitudinally of the pipe to admit air to the latter in the same manner that the slot 12 admits such air" to the pipe 5.

The lower portion of the pipe 5* is preferably larger than the upper portion thereof, giving desired rigidity, yet overcoming the necessity of having a pipe which is large and cumbersome throughout.

Either form of the invention is rather simple and inexpensive, yet will be highly efiiair blast, the windward longitudinal side of 7 said pipe being imperforate and acting as means for dividing the air blast, the leeward longitudinal side of said pipe being formed with air inlet means.

2. An air cleaner and collector comprising a suction pipe longitudinaly curved into rarcuate form and having a base for rigidly" -1nounting it with its length transverse to an air blast, saidbase having an air outlet from said pipe for connection with a saction passage, the windward longitudinal side of said pipebeing imperforate and acting as I means for dividing the air blast, the leeward longitudinal side of said pipe having air inlet means.

3. An air cleaner and collector comprising a pipe longitudinally curved into substantially circular form, and a hollow base rigidly connected with said pipe for mounting it with its length transverse to an air blast, said base communicating with the ends of the pipe and having an outlet for connection with a suction passage, the windward longitudinal side of said 3e being'imperforate and acting as, means tor dividing the air blast, the e ward eng tud na si e f said pipe havin i nlet le l -v 4. An air cleaner and collector for an internal combustion engine having a'cooling fan in front of the engine body, said cleaner and collector comprising a suction pipe between the fan and the engine body, said pipe having its length disposed transversely of the air blast generated by the fan, the front longitudinal side of said pipe being impertora te and acting as means for dividing the air blast, the rear longitudinal side of said pipe having air inlet means.
